Broken Chains: Safeguarding Rights in Drug Cases Through Strict Custody Protocols

In a significant ruling, the Supreme Court acquitted an accused drug offender because the police failed to follow the strict rules on preserving evidence. The case of People v. Reyes (G.R. No. 199271, October 19, 2016) reminds law enforcers that the procedure for handling seized drugs is not mere formality — it is a safeguard of the accused's constitutional right to be presumed innocent.

The Facts of the Case

On November 27, 2002, police conducted a buy-bust operation against Jehar Reyes in Minglanilla, Cebu. The poseur-buyers purchased one plastic pack of shabu for P1,000. After the arrest, the police frisked Reyes and recovered two more plastic packs. All three packs, weighing a total of 1.44 grams, tested positive for methamphetamine hydrochloride.

Reyes was charged with illegal sale of dangerous drugs under Section 5, Article II of Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002). Both the Regional Trial Court and the Court of Appeals convicted him, relying heavily on the presumption of regularity in the performance of official duty by the arresting officers.

The Issue

The central question was whether the prosecution had established Reyes's guilt beyond reasonable doubt, particularly whether the chain of custody of the seized drugs had been properly preserved.

The Ruling: Acquittal for Procedural Lapses

The Supreme Court reversed the conviction and acquitted Reyes. The Court identified several serious lapses in the chain of custody that cast doubt on the integrity of the evidence.

First, the confiscated items were not marked immediately after seizure. The prosecution witnesses contradicted each other on who actually placed the markings on the plastic packs — a crucial inconsistency given that marking is the starting point of the custodial link.

Second, there was no credible showing that the accused witnessed the marking process, as the law requires.

Third, no representative from the media or the Department of Justice, and no elected public official, was present during the operation or confiscation. The prosecution offered no explanation for this absence, despite the buy-bust team having two weeks of surveillance to prepare properly.

Fourth, the arresting officers failed to prepare an inventory and did not take photographs of the seized items.

The Saving Mechanism and Its Limits

Section 21 of R.A. No. 9165 and its Implementing Rules provide a saving mechanism: non-compliance will not automatically invalidate the seizure if the prosecution recognizes the lapses and justifies them, as long as the integrity and evidentiary value of the seized items are preserved.

In this case, however, the prosecution neither conceded the lapses nor offered any justification. The Court emphasized that this failure underscored the doubt about the integrity of the corpus delicti — the very drug evidence presented in court.

Presumption of Regularity vs. Presumption of Innocence

The Court made a crucial clarification: the presumption of regularity in the performance of official duty cannot prevail over the constitutional presumption of innocence. Where there is any hint of irregularity in the police procedures, the presumption of regularity stands only when no reason exists in the records to doubt the regular performance of duty.

The Court warned that allowing a mere rule of evidence to defeat the constitutionally enshrined right to be presumed innocent would subordinate a fundamental guarantee to a procedural convenience.

Practical Takeaways

• Chain of custody is critical. The prosecution must clearly and convincingly establish every link in the handling of seized drugs, from seizure to presentation in court.
• Mark immediately. Seized items should be marked at the time of seizure, or as close to the time and place as practicable. Conflicting testimony on who did the marking can break the chain.
• Witnesses matter. The presence of the accused, media representatives, DOJ representatives, and elected officials during inventory and photography is not optional — it protects against planting of evidence and frame-ups.
• Non-compliance must be explained. The saving mechanism under Section 21 only applies when the prosecution acknowledges the lapses and provides justifiable grounds for them.
• Presumption of innocence prevails. Courts cannot rely on the presumption of regularity of police duty when the records show serious procedural gaps.
